The operation of tying the common iliac artery has been performed upwards of twenty times on the human subject; first, by Dr. Wm. Gibson, of Philadelphia, in 1812, in a case of gun-shot wound; the patient died from hemorrhage in thirteen days after the operations : it was tied in March, 1827, by Valentine Mott, of New York; and in the year following by Sir P. Crampton in this city. It has also been tied by Salamon, Liston, Guthrie, Syme, Deguise, Perigof, Post, Stevens, Peace, Stanley, Hey, and Lyon. Out of all these cases nearly two-thirds of them terminated successfully. Mott's case was successful ; and as it contains a great deal of important and interesting information, we shall detail it at length.
